Need help eft1
I drove up to Utah to have a spartan, 5in exhaust, fass titanium, sinster egr cooler delete and sinster coolant filter kit installed. I messed around up there for a day and put 250 miles on the truck and drove fine. Well I drove home to day and I was hitting 154 degrees on mine eft1 and wouldn't drop pass 150. When I was in Utah it was in the 80s but today on the way home it was suppose to get close to 120 degrees and it was insanely hot. My question is, was it getting that hot because it was so hot out or do I have a bigger issue?
